Older Taurus 66 357, load is a .38 case, Lee TL158SWC cast out of ACWW, and 3.8 grains Promo. I've started carrying it with me to the pasture just about every day in hopes of getting a shot at a bean muncher. I missed him last week on the run, but today he peeked out of a brush pile to look at me from 10-15 yards away. One to the neck did the job.
